This is a little project to design and build a straight key that can be printed on a 3D printer for use with my pixie 2 or FT817.
I wanted it as simple and small as possible. As it will be used outdoors and for practice. It is next to a 2 pence piece for size comparison.
This base plate contains the ground wire from the radio. Which feeds through a channel and is soldered to a piece of PCB. Which fits snuggly in a premade cut-out.
The trigger wire is fed through a channel in the arm and fixed between two nuts.
This is the parts required to build it. Two bolts, four nuts, a spring, a piece of wire, a small piece of PCB and the parts from the 3D Printer. The L shaped piece is a bracket blank to connect it to the side of my FT817.
